The total number of genera, species and infraspecific taxa currently accepted is 60, 118 and 2, respectively. The occurrence of each taxon in the North Aegean, South Aegean and Ionian Seas is given. Knowledge gaps are pointed, with 70 taxa pending confirmation of their presence marked. Moreover, 15 excludenda and 20 inquirenda taxa are briefly discussed. In this paper is given an updated base of the Ceramiales taxa occurrence in Greece, needed for future targeted seaweed studies. Key words: Aegean Sea, red algae, Ceramiales, checklist, Ionian Sea INTRODUCTION the annotated checklists of the Mediterranean seaweed flora by RIBERA et al. (1992), GALLARDO Phycological studies on marine macroalgae et al. (1993) and GÓMEZ GARRETA et al. (2001) have been carried out along the Greek coasts included seaweeds occurring in Greece. since the early 19th century (SIBTHORP, 1813; Aiming to update the knowledge of the GREVILLE, 1826; BORY DE SAINT-VINCENT, 1832), Greek marine flora, the present work is focus- resulting in descriptions of several new species ing exclusively on the red algae of the order and genera and in records of numerous common Ceramiales Oltmanns, aiming to deliver a solid Mediterranean taxa.

Taxa are listed alphabetically. For each taxon previously applied, synonyms are provided. The N. Aegean: 103 taxa distribution of each accepted taxon is given for the three biogeographic regions: North Aegean, South Aegean and Ionian Sea (Fig. 1). Due to space limitation, only one reference is given for each region, giving priority to publications that include descriptions and/or illustration(s). Addi- tional references are available from the authors upon request. RESULTS Ionian Sea: 98 taxa The present checklist recognizes at least 120 Ceramiales species and infraspecific taxa, with- Fig. 1.
